Photoemission Temperature Measurement. Two Approaches to the Determination of the Procedural Error

Photoemission measurements of temperature in pulsed laser heating of various materials

“…The body temperature measured by the photoemission method, just as the color temperature, is higher than its actual temperature. The procedural errors of measuring the tungsten temperature at 1200, 1800, and 2600 K, determined by the technique of [2,3], are equal to 1.0. 1.9, and 6.0 K, when the device with a bialkali photocathode was used.…”

“…Laser pulse (1), response of the photomultiplier (2), and the surface temperature of a tungsten plate 60 μm thick during the first 100 μs of laser pulse action(3).…”
